Answer:

c) (4, 7)

Step-by-step explanation:

(x, y)

Put the coordinates of the points to the equation and check the equality.

y = 4x - 9

---------------------------------

A(-5, 11) → x = -5, y = 11

L = 11

R = 4(-5) - 9 = -20 - 9 = -29

L ≠ R

---------------------------------

B(-2, -1) → x = -2, y = -1

L = -1

R = 4(-2) - 9 = -8 - 9 = -17

L ≠ R

---------------------------------

C(4, 7) → x = 4, y = 7

L = 7

R = 4(4) - 9 = 16 - 9 = 7

L = R

---------------------------------

D(1, 13) → x = 1, y = 13

L = 13

R = 4(1) - 9 = 4 - 9 = -5

L ≠ R
